Equipment and function

•    Manual power adjustment with 3 speed stages.
•    Pumps with 1~ motor:
    * P2 up to 90 W: Internal protection against unacceptably high winding temperatures.
    * P2 = 180 W: Full motor protection by thermal winding contacts in combination with tripping unit.
•    Pumps with 3~ motor:
    * P2 up to 90 W: Internal protection against unacceptably high winding temperatures.
    * P2 ≥ 180 W: Full motor protection with integrated trip electronics.
    * Mains connection 3~230 V with optional switching plug.
•    Cataphoretic-coated pump housing for optimal corrosion protection.
•    Combination flange PN 6/PN 10 (with DN 40 to DN 65).
•    Thermal insulation shells for heating applications.
•    Additional functions with retrofittable Protect Module C:
    * SSM fault signal as potential-free normally closed contact.
    * SBM run signal as potential-free normally open contact.
    * "Overriding Off" control input by external potential-free contact (normally closed contact).
    * Blockage detection.
    * Full motor protection with built-in tripping.
    * Fault acknowledgement.
